Thunderbird email client intermittently freezes and shows approx 130%
CPU usage (viewed using top). Thunderbird's memort usage seems to sit
on around 2% (8 GByte installed). When the thunderbird error occurs,
the mouse moves but the system does not respond to mouse clicks. I
can [Alt] [Tab] to other applications (e.g. top in a shell window)
successfully. The mouse buttons work once I have [Alt] [Tab] away
from Thunderbird. The freeze sometimes lasts for only 30 seconds.
Other times, I end up re-booting after ~5 minutes to resolve the
lockup. Thunderbird has two email accounts registered - 1 x POP
account, and 1 x Gmail IMAP account. My .thunderbird folder is 1.7
GByte in size.
I have been using Thunderbird on 14.10 for 4 months, and for about 10
years on previous versions of Ubuntu, and have previously experienced
no problems with Thunderbird.
The problem being experienced could potentially be related to the
installation of recent updates to Thunderbird as the errors started in
the last week of January 2015, shortly after some thunderbird updates
were installed. Refer to following extract from /var/log/apt/history
showing Thunderbird updates installed on January 22, 2015:

There are no thunderbird related errors showing up in dmesg.
If Thunderbird is started from a command line, there seem to be no
useful messages/errors appearing on the command line.
I disabled the Addons one by one, and determined that the Addon which
seems to be consistently causing this problem is "Messaging Menu and
Unity Menu Integration 1.3.1".
